Description of the invention: [Technical field of invention] Especially in the process of image measurement The present invention relates to a system and method for focusing an image measurement system and method. [Prior Art] Office Automation (〇A) is indispensable in the current information informatization society. 4 In addition to using computers as the processing and storage of large amounts of data, it is used as an optical scanner (Scanner). The input devices for documents, forms and special materials have become one of the freshest equipments for computers because they can effectively use the efficiency of the poor input processing. The existing optical scanning is achieved by changing the head-to-head mechanism of the originals of different sizes (4), and the lenses of different magnifications are correspondingly matched at different sizes so that the focal length is just right for the electric and residual stomach pieces ( Cha_ 〇)_ Deviee, i. _ These lenses adopt the same total optical path, and the correct configuration of the corresponding matching position makes it correctly imaged on the electric homozygous device. "Because the lens is a reconstituted ^, ^ process will inevitably produce a little error. In order to make the lens clear imaging requirements or slightly different. Therefore, in the process of lens switching, the shadow = just = accurate imaging in the electric _ _ ± ±, and turn the optical scanning off a lens because of the lens Or the error of the installation and the accuracy of the mirror image. The announcement number of the authorized announcement on May 26th is CN 2321G22Y, and the illuminating ^^= 3" patent, the material provides - from Lin "set, set in the lens can be controlled by the whole lens, the camera positioning unit, - the coffee set, the whole 71, and - can control the" CD reading tank unit is a fresh element. When the scanner is open 1263444 When in use, it can automatically move the lens to the appropriate position for the lens imaging, so that the == silk _ whole, the lens and the electrical device, so that the optical scanner's (four) degree is greatly focused, imaging on the charge transfer The image measuring machine that is placed on the object to be tested is used to control the software in the brain. The purpose of the other object of the present invention is to provide an image autofocus system. The purpose is to provide an image autofocus method in a spider.

The function module of the user terminal computer of the invention is a brain π-including wall group m, a parameter setting module 112, a calculation mode data temporary ageing 114 and a jing module 115. input/transmission group The m test obtains the continuous image acquired by the optical lens is and ccd by the image manipulation card 12 to the user computer η = 仃 analysis processing, and the control card 13 outputs an instruction to drive the reel motor to move back and forth in the designated area and to focus The setting of the idyllic computer η is the same as the setting. The parameter setting her 112 setting parameter ^ includes setting the calculation area of the image, setting whether to filter, setting the calculation amount, wherein the calculation is stricter, the difference is a The more accurate the focus, the slower the speed; the less accurate the focus, the faster the speed. The calculation module m calculates the image sharpness and calculates the height of the image. The data temporary storage module 114 is configured to store the calculated sharpness value and the resolution z-axis position of the machine in the data storage. In the area 20, the determining module 115 is configured to determine whether the z-axis 17 has reached the set position and determine whether it is the second focus. If the z-axis does not reach the set position, an instruction to drive the z-axis motor 17 to continue to move is issued, by controlling The card 13 transmits the command to the z-axis motor 17 for movement. Referring to the third figure, it is a flowchart of the image autofocus method of the present invention. First, a focus command is issued by the client computer 11 (step 300), and then initialized. The focusing system sets some parameters and controls the Z axis of the machine to reach a position set by the user. The position is calculated by the user specifying an approximate position and a specified focusing distance, and the setting parameter refers to a calculation area of the set image. Set whether to filter and set the calculation amount, etc., the larger the calculation amount, the more accurate the calculated focus and the slower the speed; on the contrary, the less accurate the focus, the faster the speed (Step S302). The Z-axis motor 17 is further driven to move back and forth in a designated area, and the CCD 16 and the industrial optical lens 18 capture a continuous image of the Z-vehicle moved by the motor 17, and the input/output module ηι is to be captured by the image capture card 12 ( :1: 数字16 The digital image signal of the continuous image transmitted is input to the client computer 11 (step S304). The client computer 11 preprocesses the acquired image, and the preprocessing is mainly to clear the last time. 1263444 j and over-consideration image misf (the resolution of the phantom image clarity) pixel value processing method is used when the shouting image sharper, black and self-image "_= the greater the value, the gray level difference and the sum of the evaluation function , as shown below, I clear the number is 4 fields ν-ζν-ι Λ7 Λ κτ , ι ^[|/( _) / (χ 并将 所 所 所 晰 晰 晰 ( ( ( ( ( ( S3G8).
